Vitamin D Deficiency in COVID-19 Quadrupled Death Rate

Vitamin D deficiency on admission to hospital was associated with a 3.7-fold increase in the odds of dying from COVID-19, according to an observational study looking back at data from the first wave of the pandemic.

Nearly 60 percent of patients with COVID-19 were vitamin D deficient upon hospitalization, with men in the advanced stages of COVID-19 pneumonia showing the greatest deficit.

Importantly, the results were independent of comorbidities known to be affected by vitamin D deficiency, say the authors, led by Dieter De Smet, MD, from AZ Delta General Hospital, Roeselare, Belgium.

“[The findings] highlight the need for randomized controlled trials specifically targeting vitamin D–deficient patients at intake, and make a call for general avoidance of vitamin D deficiency as a safe and inexpensive possible mitigation of the SARS-CoV-2 pandemic,” say De Smet and colleagues in their article, published online November 25 in the American Journal of Clinical Pathology.

A search of reveals there are currently close to 40 ongoing intervention trials with vitamin D in COVID-19 around the world for varying purposes, including prevention, and varying forms of treatment.

Consider Vitamin D to Prevent COVID-19 Infection

With regard to the potential role in prevention, “Numerous observational studies have shown that low vitamin D levels are a major predictor for poor COVID outcomes,” notes Jacob Teitelbaum, MD, an internist who specializes in treating chronic fatigue syndrome and fibromyalgia who also has an interest in COVID-19.

“This study shows how severe a problem this is,” Teitelbaum told Medscape Medical News. “A 3.7-fold increase in death rate if someone’s vitamin D level was below 20 [ng/mL] is staggering. It is arguably one of the most important risk factors to consider.”

  1. This is very misleading article. Vitamin D(3) doesn’t prevent SARS-COV-2 infection but what it does do, is strengthen the immune system thus helping to avoid the worst effects of the virus. I caught the Bug last year and I’m sure that my recovery was speeded by having an adequate supply of Vitamin D.


    • It’s a fact that Viit D is essential to a working immune system but that also means if you haven’t got a working immune system you’re liable to be infected by all manner of nasties, not just the Bug of the Day.
